### ⭐⭐⭐⭐ Works in Lenovo M700 Tiny with Unraid 7.1.4
*by S***Y on August 26, 2025*

Very niche product that works for my very specific use case. I wanted to upgrade my Lenovo M700 Tiny with some higher speed networking as it has a DAS attached storage and Unraid on it. I was able to install it in the wireless card class that was close to the power button. The very tight fit, but was able to fold the cable under the card and route it to the back. I was able to pull the PCI brackets off the Ethernet port and use the screws and holes to attach it to an unused serial slot punch out. I used a piece of electrical tape to cover the bottom of the Ethernet port PCB to keep from shorts. It looks factory! Unraid 7.1.4 picked it up without any issue and able to see 2500 Mbps connection. (Router confirms as well) Initial speed tests seem to confirm it. Hopeful that the RTL8125 will be reliable as the Intel I219-V has been. Three complaints. First is on Amazon, the packed was crushed. Luckily it was packed in a strong plastic case. Second, the cable is very short. Even in my tiny client PC, it took some creative routing. I would appreciate a bit more length on the cable. Third, please include a screw for the M.2 please. I can understand a commodity SSD not including a screw, but this is a bit more niche. Even a cheap screw driver was included. Overall, a great way to add higher speed networking to a mini PC. Unraid worked out of the box.
